If I want to use the data on Twitter in my application, what are the restrictions? What user data should I avoid touching?
For example, if I want to collect information from certain type of tweets about users and use this information on my site as profiles for these users in my site, does this require permission from the users first or can I directly go and get the information?
I found this in the Twitter Terms of Service:
Tip We encourage and permit broad re-use of Content. The Twitter API exists to enable this.
But also found this on the Twitter API Terms:
You may not use Twitter Content or other data collected from end users of your Client to create or maintain a separate status update or social network database or service.
